I watched the first episode of the original series today, and I really enjoyed it.
I have to admit, I was pretty surprised when they killed the lawyer and his wife, I was expecting them to end up becoming part of the 7 in the title.
As for the whole dead wife thing in the new version, it's not that bad of a change for me. He did already have family killed by the Federation, so they if they just switch out his brother and sister for a wife, it's not a problem for me. Just out of curiosity which episode is the first to follow a more typical format for the show?
